nniiwnn PULL Ann LATCH.

Application filed August 5, 1925. Serial No. 45,317.

This invention relates to a device for use on tills, sate doors, doors in banks, etc., to control the opening and closing thereof and for controlling separate latching devices and signalling nieai'is. The purpose ol'? the invention is to provide a construction of this nature which, it operated in the usual manner or drawer pulls or door handles, will cruise the locking of thetills, etc, and at the same time signal such operation; whereas, it operated according to the knowledge of the intended user thereof will serve to release the till or safe door or other construction upon which it may be applied. The improved construction is intended primarily for use in bank protection systems.

The construction illustrated in the drawings is particularly designed for use on a cash drawer or till.

Fig. 1 ot the drawings is a rear view of latch mechanism operated by the drawer pull, and with the drawer and its casing and the latch housing shown in section.

Fig. 2 is a transverse vertical section taken on the line 2-2 of Fig. 1.

Fig. 3 is a horizontal sectional view taken on the line 3-3 of Fig. 2.

This invention may be carried out by means or diilerent forms of drawer or door handles, but the one illustrated in the draw ings is in the form oi a lever carried on the end of a post passing through the outer wall of a cash drawer, and this post at its inner end carries a twoarm lever, one end of which serves to move a latch or looking bolt to releasing position while the other end at the same time moves a sin'iilar bolt to locking position upon normal operations of the handie, but the post is hollow and is provided with a movable men'iber passing there tl'irough, which may be manipulated from the handle, and serves to shift the latch operating lever into position where it will only operate the latch which releases the drawer, and therefore will permit the drawer to be drawn to its openposition. If the handle is not operated in this intended manner by one having knowledge of the correct way in which to operate the handle, the drawer will not only remain locked, but electrical contacts are closed in circuits which control any desired number of locks and signalling means.

In the drawings the drawer to which the device is applied is only partly shown in sec tion at 1, and its surrounding casing, within which it slides is also only partially indicatcd at 2. The operating mechanism of the latching device is located within a casing 23 secured to the inner front wall 4: of the drawer; This wall is reinforced by a steelv plate 5, covered by a sheet metal face 6. The operating handle 7 for the drawer is rigid with a posts passing through the front wall of the drawer, and having an annular shoulder 9 bearing against the wall of the drawer, and is threaded at its end 10 to receive a nut 11, by means of which it is clamped to the casing 3. At its threaded end 10 the post 8 is provided with a transverse slot 12, as shown in Fig. 1, for receiving alatch operating bar or lever 18. When the handle 7 is K operated lever 13 is therefore compelled to rock with the post 8, and one end of the lever extends intoa recess 14 in a drawer latch 15, while the other end of the lever comes below a shoulder 16 on a drawer latch 17. Therefore, with the lever 13 in its normal position, when the handle 7 is rocked in a right hand direction, viewed from the front of the drawer, the lever 13 would bear downwardly on the shoulder 18 of latch 15, withdrawing this latch from looking position, and pressing upwardly on shoulder 16 ot' latch 17, forcing the latter into locking posit-ion with the drawer casing 2. Lever 13, however, is slidable along the slot 12 into inetl cctive position with respect to shoulder 16 on the latch or bolt 17, and in order to accomplish this result a rod 20 extends through the post 8 and through lever 13, the lever being held thereon by a nut 21. At its opposite end the rod 20 is bent to extend downwardly through the hollow space 22 in handle 7, and terminates in a button 261, in position on the inner side of handle 7 to be depressed by one finger of the operator. \Vhen so depressed the rod 20 shifts outwardly against the action 01 a coil spring 25 far enough for the lever 13 to clear shoul der 16. Then, when the lever 13 is in this position, by rockinghandle 7 the operator maycause the latch 15 to move downwardly against its spring 26, and the drawer may be pulled to open position. "When the-handie is released it and the lever 13 are returned to normal position by the spring 27. Movement of handle 7 in the opposite direction is prevented by a stop 28, against which the lever 13 normally bears. If the handle 7 is operated without depressing the button 24, the latch 15 will move out of locking position, but at the same time latch 17 will move upwardly into locking position, and also across a pair of contacts 29 in a circuit controlling any desired electromagnetic or light signals and lock operatingmechanisms.

In order to prevent accidental operation of handle 7, it is partly covered by ashield 30, and if it is attempted to operate the handle in the intended manner, but the operator should fail to depress the button 24 the required distance, he is apprised of this fact by a slight added resistance to operation of handle 7, afi'orded by the spring-pressed bolt 31 carried by latch 17 and seated in the recess 32 of a small block 33 attached to casing 3.

It is believed that the operation of this device is clear from the foregoing description, but briefly stated it consists merely in holding button 24 in depressed position while the operating handle is swung over in order that lever 13 will withdraw latch 15 without disturbing latch 17. The drawer may then be pulled to its open position. If it is attempted to open the drawer by one not having knowledge of the construction and the existence of button 24, the natural operation is merely to move handle 7. Such operation of the handle 7 while it results in drawing bolt or latch 15 downwardly into releasing position, would, at the same time cause latch 17 to move upwardly into locking position, and close the electrical circuit controlled by contacts 29.

Although but one specific embodiment of this invention has been .herein shown and described, it will be understood that numerous details of the construction shown may be altered or omitted without departing from the spirit of this invention as delined by the following claims.

I claim:

1. A pull and latch mechanism of the class described comprising a handle and post movable therewith, a latch, and. connections between said post and latch for operating the latch. said post being hollow, a movable member passing through the hollow part of said post into the handle in position to be shifted by the operator, the opposite end of said movable member being provided with means for controlling the operation of said latch.

2. A pull and latch mechanism of the class described comprising a handle and post movable therewith, a latch, and connections between said post and latch for operating the latch, said post being hollow, a movable member passing through the hollow part of said post into the handle in position to be shifted by the operator, the opposite end of said movable member being provided with means for controlling the operation of said latch, said handle being provided with a recess on its inner face and said movable mcm her being provided with an extension accessible through said recess.

3.
